Billionaire Tom Steyer has announced a presidential run and will seek the Democratic nomination. He joins a large field of candidates after one debate is already in the books. Steyer apparently changed his mind on running as he had said previously in January, he would not be running for President. Steyer has tried to make a name for himself by donating $40 million to an ad campaign aimed at pushing congress to impeach President Donald Trump. He says he plans to spend $140 million of his own money on his candidacy. Steyer made his money beginning in the 1980s when he launched the hedge fund Farallon Capital.
